Wolfgang Amadeus Mozart plays the keyboard, accompanied by his father Leopold Mozart, who holds a violin, and his sister Maria Anna ('Nannerl'), seated beside him. On the wall behind them hangs a portrait of their mother, Anna Maria Mozart, who died in 1778. The family engages in music within an elegant interior, an activity central to their lives, particularly during Wolfgang's youth. Sculptures set into the walls draw on classical models, aligning the domestic sphere with ideals of harmony, order, and cultivated taste characteristic of late 18th-century bourgeois and aristocratic interiors. This composition is based on a painting by Johann Nepomuk della Croce from around 1780–1781.
